THOMAS KENNEY, JR., OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HENRY TOLMAN, OF NENTON, MASSACHUSETTS.

ATOWHZER.

SPECIFICATION forming part of Letters Patent No. 642,130, dated January 30, 1900.

Application filed July 28,1899. Serial No. 725,399. (No mod l.)

To all whom it may concern.-

Be it known that I, THOMAS KENNEY, J12, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Atomizers, of

which the following is a specification.

This invention has relation to atomizers, and has for its object to provide a device of the class named which shall be simple in construction and highly efficient in operation.

The invention consists of an atomizer possessing the features of construction and relative arrangement of parts now to be described in detail and set forth with particularity in the appended claim.

Reference is to be had to the accompanying sheet of drawings, and to the letters marked thereon, forming a part of this specification.

Figure l illustratesa longitudinal vertical section through an atomizer embodying the invention. Fig. 2 represents a side elevation of the same.

The casing a of the atomizer is tubular, and its lower end is closed, as at b. The upper end of the casing is closed by a cap a, which is apertured to receive and guide a pistonrod (Z, on the lower end of which is a piston 6, provided with a suitable packingf. Leading from the lower end of the casing is a liquid- 30 discharge tube or duct g, having on its end'a nozzle g with a reduced dischargeaperture. Leading from a point near the middle of the casing is an air-duct 72, having its reduced end or nozzle it slightly behind the end of the nozzle g of the liquid-duct g, which latter is bent at an angle to the nozzle of the duct h.

The disinfectant or other liquid to be sprayed is introduced into the casing through a filling-spoutj, closed by a movable capj.

The operation of the device is as follows: Through the filling-spout is introduced a suf ficient quanity of the antiseptic or other liquid which it is desired to spray, the level of the liquid being below the mouth of the liquid-duot. Then the piston is thrust toward the lower end of the cylinder, and as it descends the air between itand the liquid is compressed, so as to force the liquid through the liquid-discharge duct, the air likewise escaping through its discharge-duct. As the liquid oozes in a thin stream from its nozzle the stream of air which is passing at an angle to the liquid-nozzle blows it off in a fine spray.

It will be seen that the upper portion of the leasing constitutes an aircylinder which is integral with the lower portion, which constitutes a liquid-reservoir. Hence there is no possibility of leakage of air between the said cylinder and receptacle, all the air displaced by the descent of the piston being utilized in forcing air and liquid through the two nozzles. The liquid-inletj is below the receiving end of the air-discharge tube h. Hence the liquid cannot rise above the receiving end of said tube 7L.

Having thus explained the nature of the illvention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- An atomizer comprising a cylindrical casing, an air-discharge tube extending outwardly from a point below the top of the receptacle and having an air-discharge nozzle at its outer end, the portion of the receptacle above the receiving end of said air-discharge tube constituting an air-cylinder having a cap or cover at its upper end formed to guide a piston-rod, while the portion below the said receiving end constitutes a liquid-reser\-*oir; a liquid-inlet communicating with the upper portion of the liquid receptacle at a point below the air-discharge tube, whereby the liquid is prevented from rising above the receiving end of the said tube; a liquid-outlet extending outwardly from the lower portion of the liquid-reservoir and terminating in a nozzle in operative proximity to the nozzle of the air-discharge tube; a piston fitting the said air-cylinder; and an operating-rod for said piston passing through and guided by the said cap or cover, the said air-cylinder being integral with the liquidreservoir, so that there is no joint between the two for leakage of air, whereby the entire air-pressu re caused by the descent of the piston is caused to force air and liquid through the said discharge tubes and nozzles.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS KENNIJY, JR.
